It's not the way I want to work. I want to tag or modify pictures on one 
computer or another depending my location, and then "save" it by 
rsync'ing all the collection on the other one. Digikam versions, path to 
files are the same on each computer, they are synced. It's very secure 
and comfortable...
The hack consisting in changing the UUID in AlbumRoots Table after 
rsync'ing is OK, and very simple with a tool like sqlitebrowser. It's an 
acceptable solution for me.

rsync is OK for detect tag insertion in pictures, it's perfect for me.

Yes. I think having the same version of digikam is absolutly mandatory.

Yes, I completely agree. Hours and hours of tagging... for a funny 
parsing of the collection, jumping from any friend to any location to 
any hollydays. Fantastic, but so time expensive...
